The objects and advantages of my inven tion will be readily comprehendedfrom the 15; detailed description of the drawings, where- Figure 1 is aside elevation of my improved means and portion ofa truck frame providedw1th apocketformed to receive the link and keeper elements.

Figure 2 is a cross sectional View taken on the line 22 ofFigure 1looking downwardly. Figure 3 is. a perspective View of one of a pair ofcomplementary keeper elements, as

,employed in Figure 1.

Figure 4 isa top plan view illustrating a modified form of keeperelements adapted more especially for use with the U-shape type ofhanger.

Figure 6 is a vertical sectional view taken on the line 66 of Figurelooking in the direction of the arrows.

Figure 7 is a cross sectional view taken on the line 7-7 of Figure 6looking downwardly. I, p

Figure 8 1s a perspective vlew of one of the keeoer elementsemployed'with the construc-' tiori shown in Figure 5. Figure 9 is aperspective view of a portion of truck frame provided with-my improvedintegral pocket.

The exemplification of closed in the first three figures of the drawingsis especially intended for use inconnection with the continuous orclosed link type of hanger, a portion whereof is shown at The truckframe 16, at a point adjacent to the so wheels of the truck,lie-preferably provided Figure 5 is an elevation of the constructionshown in Figure fl:-

with a projection or arm 17 the outer end whereof and on one face,namelythe face disposed toward the wheels of the truck, is pro videdwith the vertically spaced portions 18, 18 arranged to provide a socketor pocket therebetween.

The portions 18, 18 are. preferably arranged at an upward inclinationtoward theouter ends. so that the socket or pocket will decline towardthe inner closed end'thereof, Where the two portions 18, 18 arereenforcedand'pr vided with the ribs 19 formed integral'with theopposite sides of the portions.18, 18';'the ribs or integral portionsbeing provided at the forward side with an arcuateface-zas very clearlyshown in Figure 9. By reason of the formation of the arm with the ribs19, 19, the pocket between the portions 18, 18, at the inner end, isprovided with'the socket por tion 20. The lips or. projections 18', 18,ad-

' jacent to their outer ends, are provided-with the registeringbolt-receiving openings 21, 21; and the upper projection 18 is shown reenforced by the vertically, disposed vrib 22 extending lengthwise offthearm '17 and preferably taperingtoward'the outer end of the arm, asshownin Figure 9.

Where the continuous type of link hanger 15-is to be employed, keeperelements 23, one of which is shown in Figure 3, are preferably employed.Tlie'pocket, intermediate of the projections or portions 18, 18 of .thearm, are adapted to receive a pair of these keeper elements 23, whichare identical in construction, with the matchingorabuttingfaces'provided with the longitudinally disposed groove 24adaptedto' receive the upper end of the link 15'. The longitudinal sidesof the keeper elements 23, which are to be locatedwithin the pocket, areeach provided" with the angula'rlyformed shoulder 25 terminatingshortof-the ends of the keeper elements, so asto fit withintlie: socketat the innerend: of v the, pocket between theiribs 19,- 19.

The ends of the keeper elements, adjacent, to the shoulder 25, arepreferably formed arcuate as shown at 26, 26 so as to seat against thearcuate faces ofthe vertical ribs19, 19.

that with. t

t is apparent from the structuregshown e. projection or shoulder on thetop and bottom keeper elements 23 seated within the socket rearward ofthe forward faces of the ribs 19, that longitudinal movement of thekeeper elements'23 is impossible and that a proper positioning of theseelements is ensured.

The projections or extensions 18, 18 of the 3 arm 17 of the truck frame,in addition to having the outwardly upward slope as previously stated,are preferably formed to slightly diverge toward the outer ends, therebyproviding a pocketof slightly greater vertical dimensions at the outerend than at the inner end thereof. The keeper elements changeable andpermitting either keeper ele- V ment to be located either above or belowthe a hanger, with the result that easy assembly is made possible andlow cost of manufacture provided.

The forward longitudinal sides of the keeper elements 23 are each shownprovided with an arcuate-groove 28 disposed vertically .across the frontsides to receive or permit passage of a bolt 29 which is insertedthrough the registering holes 21 of the projections or extensions 18 ofthe arm; the bolt passing through'the grooves 28, causing the keeperelements 23 to be held in the pocket.

By reason of this construction and arrangement, it is apparent thatpractically no I strains are placed on the bolt 29 and that accidentaldisplacement of the keeper elements is less likely. I 7

In order to prevent the accidental loss of the retaining bolt 29 (aremote possibility with the construction shown), I prefer to provide thebolt locking means'30, the construction whereof is more clearlydisclosed in Figure 6. This locking means consists of a bendable thinsheet metal plate having an aperture at one end for passage of the bolt29, while the plate, after passage of the bolt 29 therethrough, is thenbent'upwardly and rearwardlyover the head of the .bolt, as

is shown, thus preventingv accidental displacenut on the lower end ofthe bolt.

pe'rrnit the application of the bolt locking ment of the'bolt'29 in theevent of loss of the In order to means, the upper flat face of thekeeper element 23 is provided witha depression 31, see

Figure 3, of a depth commensurate with the thickness of the keeper plate30 so as to pergitudinal movement, as well as proper bearing for theends of the pin provided.

The pocket in the arm 17 of the truck frame may be identical inconstruction to that previously described, being formed adj acent to theinner vertical rib 19 with a groove'or socket 36 to provide clearancefor the enlarged eyeletted end 35 of the U-shape hanger 32 and thuspermit free oscillation of the latter during the operation of the brakemechanism. 7 i

The keeper elements 34 have their'main or intermediate portions formedsubstantially similar to the keeper elements 23 as is apparent from acomparison of Figures 3 and 8, with their matching faces each providedwith the longitudinal groove 24 and their inner longitudinal sidesprovided with the shoulder 25 adapted to fit into the socket 20. at theinner end of the pocket between ribs 19. The keeper elements 34 at eachend are provided with an extension 37 shown formed integral with whatmay be termed the outer longitudinal side of the keeper elements; saidextension curving or extending toward the rear longitudinal side of thekeeper element and in spaced relation with the main portion thereof toprovide the sockets or slots 38 for. reception of the upper. eyelettedends 35 of the U-shapehanger 32and permit free oscillatory movement ofthe hanger 32.

The ends of the extensions 37 are enlarged as at 39 and provided ontheir'lower or matching faces with grooves 40 aligned with the groove24: to receive the ends of the hanger supporting pin 33; the outer facesof the enlargements of extension 37 being preferably provided withthe'walls 41 which close the outer ends of the grooves 40 and thusprevent longitudinal movement of the pin 33 in the composite groove 21-40.

The keepers 34 (of which a pair are emwedging fit into the gradually andslightly flared pocket between the extensions 18 of the arm 17 of thetruck frame; 7

The keeper elements 34;, as shown in th drawings, are preferably ofslightly greater transversewidththan the keeper elements @23, forthepurpose of ample strength and mu: "the keeper elements 23 to beproperly are therefore provided with the bolt-receiv restate ingapertures 42 instead of the grooves 28 as in Figure 3, so that theretaining bolt 29 will not only pass throu h the apertures 21 of theextensions 18 of the arm, but will also pass through the holes 42 in thetwo superposed keeper elements 34.

The keeper elements 34, like keeper elements 23, have been shown ontheir upper fiat faces with a similar depression 31 for the purpose ofreceiving the bolt-locking element 30 previously described.

In practice, where a continuous link 15 is employed, the upper end ofthe link is inserted into the groove 24 of the lower keeper element 23;the upper keeper element 23 is then put into position with its groovedface downwardly so that the matching grooves 24 of the two keeperelements or blocks will constitute a suitable channel whereby freeoscillatory movement of the hanger or link 15 will be permitted.

lV here the U-shape hanger 32 is employed, the supporting pin 33 ispassed through the upper eyeletted ends 35 of the hanger 32 and theintermediate part of the pin placed in the intermediate groove 24 of thelower keeper element, with the ends of the pin, namely the ends beyondthe eyeletted ends 35 of the hanger, resting in the aligned grooves 40of the extensions 37 of tne keeper element 34. The upper keeper element34 is then put into position with its grooved face downwardly so thatits grooves 24-40 may register with the grooves of the lower keeperelement and thus completely enclose or house the hanger supporting pin33.

The assembled elements (either of the construction shown in Figure 1 orof the type shown in Figure 4) are then inserted into the flaring andupwardly outwardly sloping pocket formed between the extensions 18, withthe shoulders 25 disposed into the pocket at the inner end intermediateof the ver tical ribs 19.

These shoulders not only tend to center the keeper elements in properposition, but will also prevent any lateral or sidewise movement of theelements. With the keeper elements and hanger or supporting pin andhanger in place as previously described, the

locking bolt 29 is then inserted into place thereby maintaining thekeeper elements in their wedged position in the pockets.

It is apparent from the constructions de scribed that either type ofkeeper elements may constitute an upper or a lower element as they areidentical in construction and therefore interchangeable; and it is alsoapparent that substitution of either type of hanger link may be made.

It is also evident thatno great strains are applied to the retainingbolt 29 and that accidental removal of the bolt, where the retainingmeans 30 is not employed, is also less likely because of the generalconstructioii aI id arrangement, even though the niits entire bolts'29slio'uld'be lost; while-chatter or'vibration betweenthe elements and thetruck frame is prevented and the possibility {if wearitlms inaterially'reduced; while at the" same time a considerable saving in ma terial andexpense is possible because of this general constructionand-arrangement.

While I believe the constrtictions shown "described to 'be' 'the best,embodiments or invention, certain modifications ma be made without,however, departing from the spiritof my-invention.
